SPECIFICATION forming part of Letters Patent No. 364,784, dated June 14, 1887. Application iiled'May 7, 1886. Serial No. 201,417. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH E. TYNAN, of Paterson', in the county of Passaic and State of New Jersey, have invented an Improvement in Machines for Throwing Silk, of which the following is a specification.

In machines for making organzine the silk threads are drawn off of two spools, twisted and their laid together and wound upon a third spool.

The objects of this invention are to improve the machine for twisting and laying up silk threads and forming organzine.

By my improvements I am able to obtain uniformity in the twist of the thread and great delicacy in the action of the stop mechanism, and render the belt very sensitive to the action of the ystop-motion and belt-shifter by bringing together the devices hereinafter described.

In the drawings, Figure 1 is a vertical section show-ing the sets of spindles, the driving, feeding, and stop mechanism, and the frame ofthe machine. Fig. 2 is a plan'view of the spindles and the driving-belts, cylinder, and the belt-tightener, and the braking and beltshifting mechanism. the feeding device, faller, and detector wires and guides for one set of spindles and part of the bobbins and ring-rail; and Fig. 4 is a plan at aboutthe line :v fr, Fig. 3. Fig. 5 is a plan view cf the forked guide for the drop-bar, said dropbar being in section.

The frame-work of this machine is composed of metal frames A, connected together by the spindle-rails B, and longitudinal rails or frames C, as usual in this class of machinery.

-The main shaft 1 is supported in bearings upon the frames A, and upon this shaft is the cylinder or drum 2, thatis ofsufteient length to receive all the belts in themachine, or there may be a separate drum to each belt. Upon the spindle-rails are the spindles 3 4 5, adapted to receive thespools 6,7 8. The spools 6 and 7 supply the threads that are twisted together and woundA upon the spool 8, and there is ring-rail, 9, with holes through the same for the spindles 5 and spools 8, and this ringrail is raised and loweredvin any usual manner, and upon this ring-rail is a ring and traveler for the thread passing to each spool Fig. 3 is an elevation of" 8. The threads from the spools 6 and 7 pass up and around the guide-roller l() and feedroller 11, and thence to the ring-traveler 91. The driving-roller 13 is upon a shaft, 14, a'nd this shaft receives its motion from the main shaft by a train of gearing consisting of the pinion 15 on the shaft 1, gear-wheel 16, pinion 17, and gears 18 and 19, the latter being on the shaft 14. In order to vary the speed of the driving-roller 13 in relation to the speed of the spindles 3 4 5, I make the pinion 17 changeable by placing the stud or gudgeon 22 upon which the pinion 17 and gear 1G revolve in a slot in the cross-frame 23, such slot being the are' of a circle from the main shaft l, so that the gear 16 and pinion 15 may remain in their proper relative position, whether the pinion 17 is large or small. This is of importance in silk-throwing machinery, because it allows for the proper extent of twist being introduced into the organzine or warp.

It will be seen that .in order. to revolve the drivingroller shaft 14 in the proper direction, at the opposite side of the machine a pinion, 24, is introduced between the gears 18 and 19 at that side of the machine.

In connection with my improvement, it is necessary to revolve the spindles 3, 4, and 5K4 in the proper directions and at the proper relative speeds, the spindles 3 and 4 being revolved in the same direction to twist the separate threads, and thespindle 5 in the reverse direction to lay the two threads together. The pulley on the spindle 5 should be larger than the pulleys on the spindles 3 and 4, as it doesnot have to revolve as rapidly as those spindles which twist the single threads; and it is further necessary to stop the revolution of one group of spindles when either thread in that group may break. With this object in View I provide for driving two groups .of spindles on opposite sides of the machine with one belt, and in so doing I lead the belt in such a manner that it passes for a considerable distance in-a straight line through the belt-shifters to the respective pulleys; hence thebelt is very sensitive and easily moved by the belt- Shifters, and the belt is long and drives siX pulleys; hence the number of belts is lessened and they'are easily kept in repair, and the convolutions of the belt around the drum and ICO guide-pulleys are such that the various portions of each belt run free of contact with the other portions and risk of the belt slipping is avoided.

Upon reference to Fig. 2 it will be seen that the belt 30 passes around the pulleys of the spindles 3, 4, and 5 in the following manner: From the fast pulley S4 of the spindle 4, around the fast pulley S5 ofthe spindle 5, then around the pulley 83 of the spindle 3, and across the machine to the fast pulley 94 of the spindle 4 ofthe opposite group of spindles,thence around the fast pulleys 95 and 93 of the spindles 5 and 3 respectively of that group back to the drinn 2, ovei and around beneath that drum, up over the guide-pulley 3l, thence around the drinn 2 a second time, over the guide-pulley 32 to the pulley S4 at the place of beginning. In this manner I ani able to prevent the band slipping 011 the drum, because itpasses around the same twice, and one portion of the belt does not come into contact with any other part, and the belt is very sensitive to the belt-Shifters, thereby reducing the wear on the bands and rendering the same very durable.

The guide-pulleys 3l and 32 are preferably upon an axis or gudgeon that is ata slight inclination, as shown in my Patent No. 336,027, and this axis is supported by the bent lever 33, pivoted at 34, and provided with a weight, 35, whereby the slack of the belt is taken up and the proper tension maintained on the saine.

The fast pulleys upon the spindles 3, 4, and 5 are above the loose pulleys 36 37, and the belt-shifter40 acts upon the belt to move the saine down upon the loose pulleys when the spindles are to be stopped. This belt-shifter is placed so as to act upon the belt as it approaches the spindle 4, and by depressing the belt at this point or raising it the belt will be caused to run off ofthe fast pulleys upon the loose pulleys, or the reverse, in the group of spindles.

There is a finger, 41 ,projecting from the stock of the belt-shifter and forming a brake for the spindle 5, and two spring-fingers, 42 43, which are adjacent to the spools upon the spindles 3 and 4 and form brakes for the same. These brakes are out of contact with the respective spindles or spools, except when the belt-shifter is depressed for shifting the belt from the fast to the loose pulleys. The particular forni of the belt-shifter and the respective brakes may be varied. At one side of the machine I have shown these parts as pivoted at 45 and acting by leverage when moved by the drop-bar 50. At the other side of themachine I have shown the same parts as bolted to the drop-bar 50 and rising and falling with the same; and in this case the lower end of the drop-bar is inclined, as shown at 51, so that as it moves against the guide 52 the brakes will be carried laterally and brought into contact with the respective spindles o'r spools at the saine time that the belt is shifted. It is preferable to fork the guide 52 for the inclined lower end of the drop-bar to pass through, as shown in Fig. 5.

In cases where the threads pass 011e or more times around the feed-roller one convolution is liable to run upon another and bind itto the roller, and the threads will wind upon the feedroller and forni waste, and this risk is increased where the feed-roller is driven' by contact with a feeding-drum. I avoid these difficulties by leading the threads around agrooved guide-roller and a grooved feed-roller, as hereinafter stated, so that the threads are kept separate and are not subjected to lateral pressure.

Rising above the frames A and the shaft 14 of the drivingrollers are the brackets 55, which project outwardly and are provided with vertical slots in their faces for the reception of the ends of the shaft 56, that passes through the feed-roller 11, and thereis a link, 57, projecting downwardly from the shaft 5G and having a gudgeon, 58, upon which the guide-roller 10 revolves. There is a stop, 84, projecting from the link 57 on the gudgeon 53,

and this stop takes against the periphery ol' the driviiig-roller 13 and keeps the guide-roller 10 from contact with said roller 13. The surface of the feedroller 11 is iliade smaller in the middle portion, so that the thread passing around this peitioii of the roller will not come into contact with the surface of the drivingroller 13, and in the surface ofthe guide-roller 10 there aie two grooves for the threads.

The threads from the spools 6 and 7 pass u p over the faller-wires (S0 Gl., down beneath the cylindrical guides G2 (53, up over one of the grooves in the guide-roller l0, around the feedroller` l1, back again and around the guideroller 10 in the other groove, over the feedroller Il, down against the surface of the driving-roller 13, down through the stationary eye 82, and through the eye of the detector (34 to the ring-traveler of the spool S. By passing the threads around the feed-roller and guide roller in the manner described the requisite tension is obtained for drawing the threads along, and the possibility of one convolution winding upon another convolution is entirely avoided, and by connecting the gudgeon ofthe guide-roller with the axis of the feed-roller IDO IIO

the two can be taken out and handled together,

which greatly facilitates the operations in introducing or mcnding the threads. I prefer to make use of the guide-fingers 66, pointing downwardly and in line with the axis of the respective spools 6 and 7, so that each thread will be twisted around its finger as it passes upwardly over the faller-wires and down below or through the guide, (at 62 63,) and up to the feed-roller, thus giving sufficient tension to hold down the fallcrs and prevent them stopping the machine, except when a thread breaks, and such thread will diverge from such finger to the edge of the spool as such spool revolves and twists the thread, and the two threads will be laid together by the ringtraveler, the twist extending up through the driving-roller 13.

eye of the detector 64 to the surface of the It is to be understood that :no care or atten- 'thread over the faller-wire and rollers, and as the thread is drawn upwardly and twisted by the revolution of the spool it is carried against and wrapped around said linger by the revolution of the spool from which the thread is drawn.

In case'either thread breaks, it is easily repaired, because the feed-roller 11 and guideroller 10 can be lifted together, so that the shaft 56 is above its bearings, and the threads can be passed over and then under the respective rollers and theparts returned to place 5 and to further facilitate this repairing of the threads I'inake the cylindrical guide 62 longer than the guide 63, so that the thread can easily be slipped in between the two guides by press- .ing it against the side of the projecting guide 62. Theseguides 62 and 63 are preferablyYA glass tubes slipped upon wires that project from the brackets upon the frame of the machine. A

The drop-bar is provided with a stop, 71, that rests upon the top of the jaw 70, and there isa spring, 72, that presses the stop 71-over the jaw. Upon the drop-bar is a cross-head,

73, to which are pivoted the faller-wires 60 61.

and the detector'64. These faller-wires and detector are counterbalanced, so that the weighted ends will descend when the outer ends are. not held down by the respective threads. Upon each faller-wire and detector is an upwardly-bent loop or projection, 92, adjacent to the under side of the driving-roller 13, and n this rdriving-roller 13 there are recesses 74 75, and these recesses may be at one side only, or they may be at both sides. The part of the roll'er between these recesses is plain and against it the doubled thread passes, and the portions ofthe feed-roller 11 that are in contact with the driving-roller 13 are wider than, the recesses; hence the feed-roller 11 cannot drop in to these recesses. At one side of each bracket is a lever, 80, passing beneath the shaft 56, and having at'its back endajaw through which passes the screw 81 into the drop-bar 50. The operationof these parts is that whenever either thread from the spool 6 or 7 breaks, or the organzine, passing down to the ring-traveler, breaks, the stopfmotion is brought into action by either faller-wire or 61 or the detector 64,swinging by the counterweight, so that the projection thereon passes up into either the recess 74 or 75, and the drivingvroller13, as it revolves, presses against the projection on the taller-wire or detector, forcing the drop-bar 50 .backwardly and unlatching the stop 7l, and allowingsaid dropbar to descend and shift the belt from the fast to the -loose pulleys and apply the brakes to such pulleys, and at the same time thelever 8O lifts the feed-roller 11 from contact with the driving-roller 13 and stops the feed. The

. parts remain in this position until the threads have been repaired or a fresh spool inserted, and when the threads have been placed in their proper positions the machine is started by simply pressing theouter ends of the fallerwires 60 61 and the detector 64 with the edge of the left hand and placing the thumb on the lever S0,` and thereby bringing the feed-roller .in contact with the driving-roller 13 andshifting the belt from the loose to the fast pulleys of the respective spindles,and.at the same time the loose threads are guided by the right hand as the winding progresses until the slack is taken up. These arrangements that allow the starting to be done with one hand greatly in crease the facility with which the machine can be used. f j

I do not claim, broadly, the arrangement of the three spindles, as shown in the drawings, and driving them by oneendless belt, as that forms the subj eet of my application for Patent No. 199,883, filed April 23,l 1886.

the driving-roller to act on the taller-wires they are liable to catch the threads, especially when mending such threads. This difficulty is avoided by making the recesses in the driving-roller to act upon the stop-motion.

I am aware that in drawing-heads the upper roller has been provided with a grooved tri pper and a projection within the groove to act on the stop-motion lever if the sliver breaks or is too thin. In my improvement the recesses are in the driving-roller itself and are free from the objections and difficulties herctofore experienced, where there are pins to act on the stop mechanism, and around which the threads are liable to become entangled.

' I claim as my invention 1. The combination, with the spindles 3'4 5 and their fast and loose pulleys in groups at the opposite sides of the machine, of the endless drivingbelt 30, the cylinder or drum 2, and the two guide-pulleys 31 32, the belts being passed around the respective pulleys and twice around the driving-drum, substantially as and for the purposes set forth.
